摘要
Abstract
A ultraviolet fluorescence method for the analysis of trace sulfur in aromatic hydrocarbon was established. The method was applicable to industrial aromatic content of sulfur. In order to ensure the accurate detection of trace sulfur,the operation conditions of the instrument were optimized and a series of control measures were established. The sulfide had a good linear relationship with its mass 2.0×10-9-5.0×10-8 g,the correlation coefficient was 0.9988. The recoveries of the sulfur content in aromatic hydrocarbon were 94.55％-116.67％,the relative standard deviations were 2.09％-9.23％. The limits of detection were 0.018 mg/kg. This method can applied to the determination of trace sulfur in aromatic hydrocarbon.关键词
